Blower motor wiring issues. Help needed.

Thanks, will do. Can I remove it in situ and is it easy? If its shorted will it just look burnt?

 

It removes very easily... Inspect the 2 coils on the back and see if the coils are touching each other or nothing metal touching either coil.

 

Ok, I removed the wire and fiddled with the switches and no fuses blown. I suppose that is a win. I am guessing now that I now need to remove the whole heater box and all as I can't seem to get to the red plate where the pins are. Apart from a crap load of wires there are a few other parts in the way. I will read up on how to remove it. Please correct me if I am wrong, but I guess there is no other way now other than to bench test the blower etc? Can I actually bench test it or does it need to be hooked to the car? Cheers.

 

U should be able to test it in the car! If U can get 12v directly to the blower, it should spin. I don't recall the exact configuration of the resistor wiring, but, a momentary hit w/ 12v should tell if the motor is seized. If the motor spins, look elsewhere.

 

are we fixed yet...

 

Hey thanks for thinking of me I'm on night shifts at the moment do I should be able to run a 12v wire to the pin to see if it spins. Must admit I'm a little scared of the result and whether or not it will spark or blow up or something! From what you guys have suggested hopefully it will either spin or not. I guess if nothing happens apart from the wire getting hot it has seized? I will keep you updated.

 

good luck...

 

Hey. I ran a 12v wire to that plug and initially some small arching then nothing. No noise no smoke no nothing. I replaced the wire to the post and again tried turning it on and after two to three seconds it blew the fuse again. I'm lost from here.

 

sounds like the motor is shorted out. you can buy them new.

 

Really? Where should I look? I was just this minute looking at retrofitting a waterless heater in the place of the stock one. I can get them here in Aus for about $350. Never have to do a heater core amd I wasn't keen on trying to get the ac going again anyhow. What do you think?

 

like the early VW beatles?

 

I don't think im old enough to know Maybe. I could eliminate water hoses from the engine bay etc. Bugger it....thats the way I will go. You guys have been a great help. Thanks

 

The single post on the resistor is the power supply TO the motor. Running a 12V hot wire and touching that single post is basically back-feeding the resistor. I think your issue is inside the resistor assembly. It uses a 12V source and then reduces voltage by placing different sized resistors in series with the motor to reduce the motor's speed.

Does the fan motor run if you hook your orange wire directly to a 12V source? What does the inside of your resistor look like??

 

Thanks. Did what you said and each time there is a sound like the motor engages or clunks but no movement. Sparking at the end of the wire when it touches too. It looks difficult to get the resistor off. I will try tomorrow and let you know.☺

 

Even if you go to waterless heater, you still have to have a blower. I haven't seen or heard of an automotive waterless heater in many, many years! Also, if it's not made specific for the Maverick, you have to try and fit in the car. The old VW gas heaters were not very efficient in producing heat, as far as I recall.
I think it's easier to order a blower unit and heater core and replace the one's you have. Lastly, AC is something you might want to reconsider, being as you are "Down Under".
